    • The present invention relates to a watermarking method for protecting the copyright of digital data, which includes the step of dividing each of two successive frames into at least two sub-groups, the step of adding and subtracting a value, which varies according to pixel locations, to and from a specific component value at each pixel location of the sub-groups using Just Noticeable Difference (JND) values and averages of the specific component value at pixel locations of corresponding sub-groups of the two successive frames, the step of adaptively embedding watermark information while modifying embedment intensity of the watermark information, the step of calculating the averages of the specific component values of the sub-groups, and the step of extracting watermark information using the calculated averages.
    • 本发明涉及一种用于保护数字数据版权的水印方法,其包括将两个连续帧中的每一个划分为至少两个子组的步骤,添加和减去根据像素位置而变化的值 使用Just Noticeable Difference(JND)值和在两个连续帧的相应子组的像素位置处的特定分量值的平均值,在子组的每个像素位置处的特定分量值之间和从特定分量值,自适应 在修改水印信息的嵌入强度的同时嵌入水印信息,计算子组的特定分量值的平均值的步骤以及使用所计算的平均值提取水印信息的步骤。

    • A blowing device having an air suction guide with an improved structure to reduce blowing operational noise, and an air conditioning apparatus having the blowing device. The blowing device includes a blowing fan, a fan casing placed to cover the blowing fan and having a suction port, and a suction guide provided in the suction port of the fan casing to guide inlet air to the blowing fan. The suction guide includes a flow guide part extending forward from an edge of the suction port of the fan casing by a predetermined length. Due to the flow guide part of the blowing device, the inlet air flows through the suction port at a constant flowing speed and in a state of laminar flow. Therefore, the blowing device reduces a variation in a pressure applied onto blades of the blowing fan by the inlet air, and reduces operational noise thereof.
    • 具有具有改善结构的吸气引导件以减少吹送操作噪音的吹风装置和具有吹风装置的空调设备。 吹风装置包括吹风扇,设置用于覆盖吹风扇并具有吸入口的风扇壳体,以及设置在风扇壳体的吸入口中以将入口空气引导到吹风扇的吸引引导件。 抽吸引导件包括从风扇壳体的吸入口的边缘向前延伸预定长度的流动引导部分。 由于吹送装置的流动引导部分,入口空气以恒定的流动速度和层流状态流过吸入口。 因此,吹风装置通过入口空气减少施加到吹风扇的叶片上的压力的变化,并且降低其操作噪音。
